Thrown eggs have a 1⁄8 chance to spawn a baby chicken. If successful, there is a 1⁄32 chance to spawn four baby chickens instead. If the egg was thrown at a wall at a certain angle, the chicken may spawn in the wall, suffocating the chicken.

All baby zombie variants and baby zombie pigman have a 5% chance to spawn riding a chicken, forming a chicken jockey. Since a baby zombie only occurs from 5% of zombie spawns, this means that chicken jockey spawns makes up only 0.25% of all zombie spawns.

Chickens appear to wander around aimlessly, and usually swim in water. When falling they will flap their wings quickly and fall slowly, making them immune to fall damage. Despite this, they will still avoid falling off high cliffs.

While in a loaded chunk, a chicken will lay one egg every 5 to 10 minutes (6000 to 12000 ticks), unless it is (or was) a part of a chicken jockey. If you are close enough to a chicken when it lays an egg, a popping sound can be heard.

Chicks do not lay eggs. Due to their small size, they can pass through openings even smaller than a full block, though not willingly. A chick's height is somewhere in between 0.51 to 0.80 blocks.

When swimming, chicks need only one block of air above their heads. Full-grown chickens need two blocks of air above their heads or else they will take damage when they float up and will eventually die.

IsChickenJockey: 1 or 0 (true/false) - Whether or not the chicken is a jockey for a baby zombie. If true, the chicken can naturally despawn and drops 10 experience upon death instead of 1-3. Baby zombies can still control a ridden chicken even if this is set false.

EggLayTime: Number of ticks until the chicken lays its egg. Laying occurs at 0 and this timer gets reset to a new random value between 6000 and 12000.

Note: This video is outdated, Chickens are bred from seeds instead of wheat. Also, the video was made before other flying mobs were implemented, as it states the chicken is the only mob in the overworld that can fly.

When a chicken is killed off a ledge, the corpse also falls more slowly than normal, and the wings still make a flapping animation.

Chickens are able to "hide" within hoppers due to their small size, protecting them from lava or water that might be directly on top of the hopper.

A few weeks before the end of Beta, Notch tweeted that he changed the chickens to ducks,[1] causing a turmoil on Twitter. A few days later, Jeb, still getting feedback on the idea, stated that it was just a joke.[2]

While you are loading/creating/exiting a world on Legacy Console Edition, the message that appears can say "Is it a Chicken, or a duck?". Also, the summary for the mobs avatars at the end says "... and a chicken... Or is it a duck?".

The changelog for Pocket Edition 0.3.0 referred to chickens as ducks.[3]
